There have many three-dimensional shape of the object in your brain that are wanted to share, but do not know how to express? How to "sketch" the three-dimensional image in your mind? 3D modeling technology can help us construct the most intuitive and understandable three-dimensional model. The use of floor plan interpret the three-dimensional object process－the most direct and effective expression of our ideas. We have designed many paradigms so that people can quickly understand the logic of using 3D CAD software Sketchup and drawing skills, from introduction to advanced, and introduce SketchUp 3D modeling technologies. After completing "3D CAD Fundamental", it is no longer difficult to draw ideas that are beyond imagination with 3D modeling technology! The goal of this course is to construct a three-dimensional model, with the computer as the main teaching material, to enrich the fun paradigm and the complete drawing process. Step-by-step teach you how to use Sketchup's 3D modeling software technology. With the completion of "3D CAD Fundamental", you will be able to realize the 3D objects that exist in the imagination through 3D modeling!

The third example, Beach ball is designed for learners to be familiar with [Circle], [Follow me], [Rotate] and [Paint Bucket]. Learners will understand how to draw a sphere using [Circle] and [Follow Me], how to use [Rotate] and [Copy] to draw the surface of the sphere and how to use selection tricks to delete all the unnecessary planes. The module also includes the methods of using [Paint bucket] to finish the beach ball.

[MUSIC] Greetings to all. In today's class, we will introduce a select tool. This is very basic, easy, and important tool. We will use a cylinder to demonstrate these tools. Let's get started. First, we'll choose the select tool, forward click and then drag to the right. We will create a temporary selection path and only what's completely inside the box will be selected. For example, if we select the upper part of the cylinder, a culture is not completely selected. So we can see that we end up only selecting 3 quarter of the cylinder's top face, this way is known as Crossing selection which is more efficient and will produce with less error in the selection. When the model is complicated or when objects that we want to select overlap, but if we click and drag to the left, let's try it. The selection box shows some dashed lines, and we can see that anything completely or partially inside the box becomes selected. This way its called window selection. It's a better option for moving big sized entities. We can select the whole object faster. When we are selecting multiple entities, or objects, it's easy to select the wrong one, or miss the entity they wanted. We can fix the issue by changing the entity selection status. In other words, we can select and unselect the entity or deselect or select the entity by pressing the Shift key and click the entity. The Shift key can also be used with the selection box. While we are selecting the upper part of the cylinder we hold down the Shift key and then click and drag to the right. Now what is completely inside the selection box is added to the first selection once we release the mouse button. In today's class, we learned the functions offered by the select tool, like click and check to make a selection box. Now we know that the selection result depends on which way we check. We also learned that we can use Shift key, and add or subtract from the selection set. And the Shift key can also be used with the selection box so that we can select entities precisely and readily. Let's stop learning for now. Goodbye. [MUSIC]
